PHILADELPHIA (CBS) – Philadelphia’s dive bars will be the subject of a free program, tonight, at the Free Library of Philadelphia. Two recent books by local authors focus on those institutions and library officials are hoping to attract some younger patrons by having them speak.

Library co-coordinator Dan Shiffner says the library has a problem, “We tend to do very well with people who are still in school, then they go off to college and they kind of disappear until they have kids again.”

Shiffner says the library has a lot to offer that ‘missing’ age group: free music downloads, eBooks, DVD’s and more. He figures they’ll realize that if he can get them in the building, and how better to do that than with a program about drinking?

Anyone visiting the library even has a chance to become the mayor of the library on Foursquare.

“Not only is the central library on Foursquare, we have 52 locations you could become the mayor of.”

Shiffner hopes tonight’s program (click here for more information), featuring the author of the guide book Philadelphia’s Best Dive Bars: Drinking and Diving in the City of Brotherly Love, will introduce all these news features to the temporarily lost generation.

“(Chuckles) I mean, I would hate to say it’s because younger people go to bars…” Sarah Stolfa, another of tonight’s featured speakers, published a photo book called The Regulars about her years bartending at McGlinchey’s, “Maybe because young people are more active in night life?”

Shiffner hopes tonight, young people will see the life in the Library.
